Gas hydrate reservoir quality enhanced by framboidal pyrite formation

Gas hydrate enrichment mechanisms and reservoir characteristics are crucial for understanding their resource potential and role in the global carbon cycle. Traditional models emphasize coarse-grained sediments as primary hosts for hydrates, but recent studies show significant accumulations also occur in fine-grained systems. However, the influence of authigenic minerals, particularly porous framboidal pyrite, on reservoir properties in such settings remains poorly understood. This study examines
